SET-BAR MECHANISM FOR PERFORATING-MACHINES.

Application filed November 20, 1917 To all a'Lo/n it muy conf-ern lie it. known that 1, lliLLmn lV. Lasniin. a citizen of the linitcdtates. residing in borough ot Brooklyn` in thc county ot Kings and State ot New York` have invented certain new and useful Improvements in Set- 'lar Mechanisms for l)ertoating-MachincS, ot' which the following is a specitication.

This invention relates to machines tor periorating cards for use in accounting` ma chines or for other purposes.

One of the main objects of the invention is to provide improved actuating mechanism in which, in a single row of pertorating punches. only one punch'will be actuated at a time to the exclusion of the others. in which the actuation ot' a second punch in the same row will sui-el;r release the punches previously actuated in such row.

Other objects ot the invention are to provide meansfor automatically releasing before the punches are reset tor punching the next cardv` all or a part of the punches which have been previously set.

Another object of the invention lis `to pi'ovide means for holding certain of the punches in operative position during and throughout the punching ol a series of cards, without having manualltT to reset such punches for each card of the series.

These and other objects` capabilities and advantages of the invention will appear trom the subjoined detailed description ot one embodiment oi the invention, illustrated in the accompanying drawings, in which Figure l is a sectional view of a perforator equipped with the present improvements;

troni which the cards to be ei"lorated are ted to a position between theI die. plate 1Q and the punch guide plate 1&3 to cooperate with punches 1l mounted in the pcrforations ot the guide plate 1l-5 with their heads 'l5 nor1na.ll Y resting on the plate lt. From the. plates 12 and 1I?) the cards are discharged into the receptacle 1T after having been perforated. The plates 1'2 and 13 are adapted to be vertically reciprocated so that the punches l-l ma)v cooperate with the setting pins 1S to punch the card, in which operation the punches 11i which have no setting members such as the pins 1S or setting bar 19 depressed in alinement with thernwill rise with the plates 1'2 and 13 while those, punches 1l which are obstructed in theirupward movement by depressed setting-pins 1S will perfor-ate the card. For each punch 1l there is provided a setting pin 1S disposed in alinement with and directlv above the same.

Above each setting pin 18, is vertically slidahlv disposed a setting bar 19 mounted and guided in the alined openings of plates Q0 carried on cross pieces 21, on which cross pieces there are carried a pair of end plates 2'2. On each pin 1S there is provided a collar between which collars and the lmverplate 23 the springs 24 are strained. whereby the pins 1S and the bars 19 are vieldably held in raised position. Along the edge of the bars 19 there is provided an upper recess and a lower recess Q6 which provide an upper abutment shoulder Q7, a lower cam .tace 29 and a connecting rounded upper cani face 30 merging into said upper shoulder and said lower cam face.

Said recesses 25 and 26 cooperate with latchinoj shoulders 32 provided on the teeth 33 ot the anchoring nieanssuch as the latch bars 34 slidablv mountedfin openings in the lower part otsaid end plates 22.

The recesses 25 and 26 of each row ot bars 19 face in the same direction,l a latch bar being provided with each row. of `bars 19 so that a single latchbar may coperate with therecesses of all the bars of thatparticular' row. f

The latching shoulders of thelatch bars 34 are normall7 maintained in contact with the bars 19 by means of springs 86 held in place upon the outer face oi. one ot the end plates 22 by means of the clamping* plate 28, the ende of seid springs engaging in per` depressed bar.

which is in registration with the plungers.

44,V which bar 19 upon being depressed will thrust the associated latch bar endwise until the shoulder 32 enters into the upper recess and over the upper shoulder 27 of such The latching shoulder 32 normally engages in the 'lower recess 26.

Immediately after such bar 19 is depressed, the plunger 44 is released and the carriage advanced so thatthe plungers -44 will register with the neXt succeeding row of bars 19.

This advance of the carriage 44 will continue until the entire record has been set for perforation, whereupon the lates 12 and 13 will rise so thatthe punc es 14 will be raised, except those that are obstructed by depresed bars 19 and depressed pins 18,

whereupon the obstructed punches willpe'r? forate the card to reduce a corresponding record thereon, w le' those punches 14 which are in alinement with bars .19 andpins-18 which have not been depressed, will rise with the card.

Whenever a bar 19 is depressed and the -lower cam face 29 pushes back the shoulder 32, any -shoulder 32 which has been previously in engagement with an upper shoulder 27 will be released, the shoulder 32 passing to the rounded cam face 30, whereupon upward movement of the bar 19 induced by the spring 24 will'cause the cam face 30 to force the l'atching shoulder 32 fully back, so

that vthere `will be no danger that the said previously depressed setting bar will not be.

released.-

this arrangement extreme accuracy inthe construction of the latching shouldersx32and the upper cam face 30 `is not necessary, since whenever a setting bar 19 becomes depressed the latchingshoulders must bet-hereby pushed back as far as the extreme outer point of the upper cam face .30, while `in order to release any previously depressed setting bar it is only necessary .that the latching shoulder 32 be pushed back far enough-to clear the upper shoulder 27.

It will be seen that from the above arrangement it is impossible for two setting bars ofthe'same row to remain .depressed at the same time, since-fthe depression Aof any latchbar will surely. rlelease all other devpre'ssed bars of the same row. By this arrangement a wrongly depressed setting bar is automatically released on the actuation of the proper setting bar.

and release all of the setting bars as the carriage is moved forwardly or backwardly.v Said roller is located forwardly of the transverse vertical plane passing through said plungers 44 so -that as the carriage moves forward no setting bar which has just been set will bereleased, but any setting bar which may have been accidentally previously depressed will be released, and

`all of the setting bars will be depressed on the rearward return ofthe .carriage after a card has been punched.

, It .is often desirable in certain operations that certain combinations of punches and their setting bars remain depressed so -that corresponding. .combinations of holes be punched on every card throughout the whole series without the necessity of resetting the punches for each card inthe ordinary manner. To this end, I have provided locking keys 50 in alinement with the respective latch bars 34' and slida'ble toward -oraway from therack bars and Yfrictionally held in deep grooves-or slots 51 in the block 52 carried.on the cross rod 53. In order to lock the keys in inner or outer position, there is provided a locking plate 54 carried on the outer face of said block 52 and adapted to Iengage in the inner notch 56 or the outer notch 57 of the key 50. As is obvious, when the key is in outer position, as shown by the full lines, the latch bar 34 is free .to reciprocate, as has been explained. On the other hand` when the key is moved to the inner position, as shown by the ldotted lines of Fig. 2, the latch bar is held against reciprocation and any combination of setting bars that have been depressed must remain depressed so long as the keys`50 associated with'their latch b ars remains in locking po sition.

It is obvious that various changes and modilications may be made to the details of construction without' departing-from the general s'pirito'f the invention as claimed. y
